Annotation Interface SpaceIndex

@Target(METHOD) @Retention(RUNTIME) @Repeatable(SpaceIndexes.class) public @interface SpaceIndex
 Defines a space index.
 Can be defined on the property getter or as part of @SpaceIndexes when multiple indexes are
 used.

 Indexes on nested object properties are defined on the nested object getter.

 For example:

 
  To index the 'socialSecurity' property using extended indexing:
  1. @SpaceIndex(type = IndexType.EXTENDED)
     public long getSocialSecurity() {
 return socialSecurity;
 }

 To index 'personalInfo.name':
  2. @SpaceIndex(path = "name")
     public Info getPersonalInfo() {
 return personalInfo;
 }
